  • Patent number: 10501829
    Abstract: A method for producing a structural sheet metal component formed from an aluminum alloy for a motor vehicle includes providing an aluminum sheet blank in a state T4 or T5 or T6 or T7, heating the aluminum sheet blank to a heating temperature between 100° C. and 450° C., forming the aluminum sheet blank to a structural sheet metal component, and heat post-treatment of the formed structural sheet metal component.

  • Publication number: 20180236950
    Abstract: A motor vehicle sheet metal molding of the invention is produced by hot forming from a metal sheet composed of an aluminum alloy which cannot be precipitation hardened, which contains at least magnesium and optionally manganese in addition to aluminum as alloy component. The motor vehicle sheet metal molding after forming has, at least locally, degrees of deformation which are above the forming limit curve of the aluminum alloy at room temperature. To produce the motor vehicle sheet metal molding, the metal sheet is heated at least locally to a temperature in the range from 200° C. to 400° C. over a period of from 1 to 60 seconds. The heated metal sheet is subsequently placed in a forming tool of a forming press and formed to produce the motor vehicle sheet metal molding.

  • Publication number: 20130127197
    Abstract: A motor vehicle sheet metal molding of the invention is produced by hot forming from a metal sheet composed of an aluminum alloy which cannot be precipitation hardened, which sheet is in the material state H12, H14, H16, H18, H19, H22, H24, H26, H28, H32, H34, H36 or H38 in accordance with the European standard EN515:1993 and contains at least magnesium and optionally manganese in addition to aluminum as alloy component. The motor vehicle sheet metal molding after forming has, at least locally, degrees of deformation which are above the forming limit curve of the aluminum alloy at room temperature. To produce the motor vehicle sheet metal molding, the metal sheet is heated at least locally to a temperature in the range from 200° C. to 400° C. over a period of from 1 to 60 seconds. The heated metal sheet is subsequently placed in a forming tool of a forming press and formed to produce the motor vehicle sheet metal molding.

  • Publication number: 20120018422
    Abstract: A region of a structural part, which is made of a precipitation-hardened aluminum alloy, is inductively heated to a temperature between 100° C. and 300° C. for a maximum time period of one minute. After undergoing the heating process, the region of the structural part is mechanically shaped by a forming tool.

  • Patent number: 7971887
    Abstract: In a method of making a subframe of a motor vehicle profile elements made of hollow sections of steel are placed in a casting tool. Subsequently, aluminum material is filled into the casting tool to casting around the profile elements so as to form plural cast nodes on the profile elements in spaced-apart relationship.

  • Publication number: 20090243312
    Abstract: A crash box for incorporation between a bumper beam and a side rail of a motor vehicle includes an outer tube which is made of a hardened steel material, and an inner tube which is held in the outer tube in a way that the inner and outer tubes are movable in relation to one another. When shifted by the outer tube, the inner tube deforms to thereby convert impact energy in deformation energy, thereby decreasing electric energy.
